Answer:
1) x = 75°
2) x = 180° - 2×40° = 180° - 80° = 100°
3) x = 180° - 2×73° = 180° - 146° = 34°
4) x = (180° - 122°) : 2 = 58° : 2 = 29°
5) x = 90° - (180° - 80°) : 2 = 90° - 100° : 2 = 90° - 50° = 40°

Answers
C + V = A + 2
Where,
C = Number of faces
V = Number of vertices
A = Number of edges
Substituting values we have:
C + 22 = 34 + 2
Clearing C we have:
C = 34 + 2-22
C = 14

Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are
The sum of these x -coordinates is
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus, and we solve for x
Using Zero Factor Theorem: = 0 if and only if = 0 or = 0
The solutions are:
The sum of these x -coordinates is
We can check our work with the graph of the two polynomials.
O y = 0.5 (x - 2)(+ 8)
O y = 0.5(x2 -2x - 16)
O y = 0.5 (x2 -2x + 16)
Answers
Answer:
y = 0.5 (x^2 -2x + 16) has a y-intercept of 8.
Step-by-step explanation:
The x-coordinate of every y-intercept is zero. To determine which of the four quadratics given here has a y-intercept of 8, we need only substitute 0 for x in each; if the result is 8, we've found the desired quadratic.
O y = 0.5(x + 2)(x + 4) becomes y = 0.5(2)(4) = 4 (reject this answer)
O y = 0.5 (x - 2)(x + 8) becomes y = 0.5(-2)(8) = -8 (reject)
O y = 0.5(x2 -2x - 16) becomes y = 0.5(-16) = -8 (reject)
O y = 0.5 (x2 -2x + 16) becomes y = 0.5(16) = 8 This is correct; that '8' represents the y-intercept (0, 8).
